I have a stock Dj5 with the strait 6 in it with a load sludge in the oil system. If the engine dies i would like to replace it if its cheaper than a rebuild. I would like to know the options for the 727 tras bolt patterns. I have been looking over older threads but cant seem to sift through the i want to convert this to 4x4 threads. I would like 4 cylinder to 8 cylinder options. Also which would would be the most likely to have FI already. thank and Have fun

If any one can post some links to DJ5 forums ill search there. I have not had the best of luck on my own. This is my first jeep and i have no desire to go 4x4. I want to just drive it around town. I have been looking at the amc 4 cylinder but cant find if it will bolt up to the 727. also the 4.0L engin which is supposed to last forever. I do know that since it is a jeep trans mopar engines wont work. I have never done a engine swap and since mine is dam near striped down to only the essentials i think i could do it. Please Help and Thanks.

the 4.0 is a derivative of the AMC 258,so although a mopar design change,anything the AMC 258/232 will bolt to, a 4.0 will bolt to.I am not familiar with your model,so I am just commenting on the engine block.Try switching over to rotella 15-40 to clean the sludge.Do a search for "Rotella" and you will find many threads about this.It may run for a decade just like it is.

this is the engine in it 232 cu in (3.8 L) AMC Straight-6 engine. Its blowing gray smoke on start and has a definite hiss not sure which cylinder cuz on compression testing the gauge was all crap. Ill have it checked professionally. BTW Thank you for the response
